For example – one of the killer new features for me as a developer is the way the start menu no longer creates columns going across the page when there are a large number of software packages installed. I had the “pleasure” of going back and using a Windows 2000 desktop last week, I can tell you now that a short amount of time doing that made me appreciate how much more productive I am on the Vista platform.

What operating system upgrades do is set a baseline which can shorthand discussions, for example, because I know that Vista is going to ship with WPF, WCF and WF I can simply say “you must be running Windows Vista to run this software”.

I think that everyone has forgotten that the thing that drives platform adoption – applications. Vista will make desktop applications sexy again – irresistably sexy, and that will drive Vista sales.
